Tech Stack
Tag name is followed by "@" symbol and proficiency level value.
About proficiency levels:
- 1-2 — basic awareness. Minimal hands-on experience, and a rudimentary understanding of the technology's purpose;
- 3-6 — daily use. Comfortable and regular usage, capable of handling common tasks and challenges related to the technology;
- 7-9 — you are an expert, you can teach others, you know all the pitfalls and tricks;
- 10 — exceptional knowledge, comprehensive understanding, and adeptness in all aspects of the technology, including advanced problem-solving. Think twice before claiming or demanding such level.

About the Team
The Codex App team builds and maintains the Codex desktop app and IDE extension—the primary ways developers interact with Codex. The goal is to make AI feel like a real software engineering teammate inside real workflows: editing code, running tasks, reviewing changes, and coordinating long-running work.
The team sits at the intersection of research, product, and design. It ships quickly, learns from real usage, and continuously refines both the experience and the harness that connects users to the model.
About the Role
The team is hiring a Frontend Software Engineer to build a top-tier desktop experience and advance the interface for working with agents. This is a craft-focused role involving close collaboration with design to prototype, iterate, and polish new interaction models, then turn them into reliable, high-performance products.
The role will help define what great human-agent collaboration looks like, including what belongs in the UI, how state is represented, how progress and uncertainty are communicated, and how users stay oriented across long-running and multi-step work.
Responsibilities
- Build and ship polished, high-performance UI across the Codex desktop app and IDE extension.
- Partner closely with design to turn prototypes into production-quality experiences, including layout, motion, typography, and interaction details.
- Iterate on future interfaces for interacting with agents, including delegation, task timelines, status and progress, handoffs, review, and control surfaces.
- Own frontend architecture decisions involving component systems, state management, navigation, and rendering performance.
- Improve quality and reliability through testing, instrumentation, and thoughtful UX for failure modes.
- Collaborate with platform, model, and backend partners to integrate new capabilities into cohesive product flows.
Requirements
- Strong experience with modern frontend stacks, including React and TypeScript.
- A high standard for UI craft and attention to detail.
- Interest in design engineering and balancing detailed execution with development velocity.
- Experience building desktop-caliber product experiences with Electron or similar technologies.
- Care for performance, responsiveness, and polished user experiences.
- Ability to explore ambiguous problems and iterate rapidly with design and product teams.
- Ability to think in terms of end-to-end workflows rather than isolated screens.
- Experience with developer tools or IDE extensions is a plus.
